Substance of the Year 2006
Sudan 1 is a red dye used to colour solvents, oils, waxes, petrol, and floor polishes. Because Sudan 1 is linked with cancer, EU regulations prevent it from being used in food.
Yet, it was discovered in 2005 that Sudan 1 had contaminated a chilli powder used in a brand of Worcestershire sauce.
Hundreds of products were swiftly withdrawn from sale. Further concerns were raised in April 2005 after the discovery that another carcinogenic dye, Para Red (C16H11N3O3), had contaminated some foodstuffs.
